This invention relates to a smokers pipe and more particularly to such apipe that is adapted to supply relatively cool and clean tobacco smoketo the user.

It is a primary object of the invention to provide a smokers pipe havingnovel and improved features of construction.

Another object of the invention is to provide a smokers pipe having itsparts so constructed and arranged that smoke of tobacco consumed thereinis filtered and flows along a circuitous path whereby the smoke iscleansed and cooled prior to withdrawal through the pipe stem.

A further object of the invention is to provide a smokers pipe of thecharacter indicated that may be readily dismantled, cleaned andreassembled as required.

A still further object of the invention is to provide a smokers pipethat is adapted to perform its intended functions in a trouble-free andeffective manner.

One of the outstanding features of the invention resides in so arranginga tobacco pipe bowl unit with respect to a stem unit that the bowl unitis rotatable relative to the stem unit. The bowl unit preferablycomprises an upstanding tubular first member having a plurality oflongitudinal passages which communicate with the lower portion of theinterior of the tubular member. One or more openings establish directcommunication between the passages and the exterior of the first tubularmember. The stem unit comprises a second tubular member coaxial withand. surrounding the first tubular member. The first and second tubularmembers are relatively rotatable. Attached to the second tubular memberis a stem that may consist of one or more pieces and that has a singlethrough passage. A tubular detent is slidable in the stem passage and isadapted to register with any selected one of the aforesaid openings,depending on the,

angular position of the first tubular member with respect to the secondtubular member. Resilient means, preferably a compression spring withinthe stem passage, normally and yieldingly maintains the tubular detentin registration with the selected opening.

One or more of the longitudinal passages in the first tubular member maybe provided with suitable removable absorbent filters, suchas'conventional pipe cleaners, that serve to absorb moisture, tarrysubstances and the like in the tobacco smoke. These filters may bereadily inserted in or removed from the longitudinal passages asrequired. Further, the pipe may be 2 readily dismantled, cleaned andthen reassembled.

This invention is adapted to be advantageously employed withconventional style pipes, i. e., pipes wherein the stem unit ispositioned at or proximate the bottom of the bowl, or with underslungtypes of pipes, wherein a substantial portion of the bowl unit projectsbelow the juncture of the stem and the pipe bowl. When the invention isused with conventional style pipes, the second tubular member is closedat its lower end to serve as the bottom wall of the pipe. When theinvention is applied to underslung types of pipes, the second tubularmember is preferably in the form of a ring.

The enumerated objects, as well as other objects, together with theadvantages of the invention, will be readily understood by personsskilled in the art upon reference to the following detailed descriptiontaken in conjunction with the annexed drawing which respectivelydescribe and illustrate several forms of pipes constructed in accordancewtih the invention.

Figure 9 is a view taken along line 9-9 of Figure 8.

Referring now to the drawing wherein like reference characters denotecorresponding parts throughout the several views, there is illustratedin Figures 1-4 an underslung type of smokers pipe embodying theinvention. The pipe may be considered as consisting of two units,namely, a bowl unit [0 and a stem unit H. The bowl unit comprises anupstanding tubular member I2, open and externally threaded at each end.Tubular member I2 is formed with a plurality of spaced vertical throughpassage l3, each of which is adapted to accommodate an absorbent filterH for removing moisture, tarry substances or the like that may beentrained in the tobacco smoke. Such filters may, if desired, be made ofconvenient lengths of conventional cotton pipe cleaners. Lateralpassages l5 establish communication between the lower end of eachpassage l3 and the interior of tubular member I2. The tubular member isalso provided with a plurality of angularly spaced, concave lateralopenings l6, arranged intermediate its ends and establishing directcommunication between corresponding longitudinal passages and theexterior of the tubular member. An internally threaded hollow closuremember 11 engages the lower threads in tubular member L2 and serves asthe bottom wall of the pipe. As is best shown in Figure 2, closure ii ispositioned across the lower extremities of passages l3. M u d at th u pr en o ub la m mbe 2 is an annular member consisting of an internallythreaded ring I8, which engages the threaded upper end of member l2, andan inwardly projecting flange [9 that extends, across the upper ext mityf a h a s ge 3- sit on d W l within and coaxi l with tubular member I2is a hol w l er 20 t a te minate s htly ab ve the upper surface ofclosure [1 whereby tobacco smokecreated in the liner is free to enterlateral passages 15 and longitudinal passages i3. Liner is preferablymade of briar.

Stem unit I l comprises a tubular support mem.- ber 9,1 ring 2| having atubular extension that is integral and preferably normal to the axisthereof. An intermediate tubular connector 23 is threaded at its forwardend for engagement with corresponding threads in the free end of member2.- T ot e end o nnector 23 projects into and frictionally engages a bitmember 24. Extens on mem r 22 conn tor 23 and t 4 o s ute th stem of hep pe d defi e a m passage 25. A tubular detent 25 rounded at its forwardend, as indicated at 2'] in Figure 2, is

For t e urpose o b ie y o lin n t e ration of the pipe constructionshown in Fi ures 1-4, it is first ass med th the i e is sem l and theparts are in the relative position shown n F u It further assume h the bw unit contains tobacco to the level indicated at L Fig r 2., n he.cours of sm i sm passes o n y in l ner 28, alo g lateral a sage l5,upwardly through passage [3, thence through apertured detent 26 andfinally through stem passage 25. It will be observed that with thisarrangement the pipe stem communicates with only the particularlongitudinal passage 13 that communicates by way of corresponding con-.cave opening [6 with detent 26 When the filter that passage l3 becomestarry or moist, the bowl unit may be rotated relative to the stem unitso as to bring detent 26 into registry with an h c a e ope n 6 hat cmmunicate ith a assage it ha ing a clean fi ter- The modification of theinvention shown in Figures 5-7 likewise consists of a bowl unit 30 and astem unit 3|. Here the bowl unit comprises a first tubular member 32preferably made of briar. Member 32 is externally threaded at its upperend and is provided with a plurality of vertical through passages 33.Alternate passages 33 communicate directly with the exterior of member32 by way of concave lateral openings 34. Intercommunication is eifectedbet-ween passages 33 by arcuate grooves 35 (Figure '7) in the upper endof member 32. The lower end of member '32 has an annular groove 36(Figure 5). Lateral openings 31' establish communication between theinterior of member 32 and alternate passages 33. As in the case of thefirst described form of the invention, this modification contemplatesusing filters I4 in passages 33, and the annular member consisting ofring l8 and flange l9.

Stem unit 3| comprises a tubular member 40, closed at its bottom end 4]and having an internal annular ridge 42 that registers with an: nulargroove 3i; in tubular member 32. Unit 31 is otherwise the same as unitH.

The path of the tobacco smoke through the pipe is indicated by thearrows in Figures 5-7. As will be noted, this path is circuitous and thesmoke in the course of its passage through the pipe is both cleansed andcooled.

Figures 3 and 9 illustrate another modification of the invention andshow a pipe consisting of a bowl unit 45 and a stem unit 46. Bowl unit45 comprises a tubular member 4?, preferably made of briar, and having aplurality of longitudinal passages 48 formed in its wall. Successivepairs of passages 48 are connected at the bottom of the tubular memberby lower arcuate grooves 49. The lOngitudinal passages are similarlyconnected at their upper ends by arcuate grooves arranged in the mannershown in Figure 7. The described arrangement of longitudinal passagesand arcu ate passages defines a si gle circuitous path. A concaveopening 5| establishes direct communication between one of thelongitudinal passages and the exterior of the tubular member. Anotheropening 52 establishes direct communication between another longitudinalpassage and the interior of the tubular member.

Stern unit 46 is similar to unit 3| of the first described modificationand comprises a tubular member 54 closed at its lower end 55.

The smoke enters passage 52, moves upwardly alon the on itudina passa 48c mmunicatin with passage 52, flows across the top arcuate groove,downwardly through the next longitudinal passa e, flows across the lowerarcuate passage 49 communicating therewith, etc., and finally istransmitted by the last longitudinal passage into opening 5!, thencethrough detent 26 and finally into stem passage 25.

Thus it will be seen that the constructions herein shown and describedare well adapted to accomplish the objects of the present invention. Itwill be understood, however, that the invention may be embodiedotherwise than as here shown, and that in the forms illustrated, certainob! vious changes in construction may be made. Therefore, I do not wishto be limited precisely to the constructions herein shown except as maybe required by the appended claims considered with reference to theprior art.
